Netflix has been rocked by a fresh shake-up in its all-time Korean rankings after a new drama stormed past one of the platform’s biggest global hits, leaving industry watchers stunned and fans scrambling to keep up with the rapidly changing leaderboard.

The series, Teach You a Lesson, has continued its extraordinary global run, now officially overtaking The Glory, the internationally acclaimed revenge drama starring Song Hye-kyo, to secure a place among Netflix’s top five most-watched Korean originals of all time. The milestone marks a significant turning point in the streaming giant’s content landscape, as a newer title rapidly dethrones one of the most talked-about Korean series in recent years.

According to Netflix’s Tudum weekly rankings covering June 22 to June 28, the breakout drama continued to dominate the Global Top 10 Non-English TV Shows chart. It didn’t just hold its position at the top—it reinforced it. The series once again landed at No. 1 globally for non-English television, extending its reign to four consecutive weeks at the summit, a feat that underlines its remarkable staying power in an increasingly competitive streaming market.

During the latest tracking week, Teach You a Lesson pulled in approximately 7.3 million views. Netflix calculates these figures by dividing total viewing hours by runtime, a method designed to standardise global consumption data across different episode lengths and formats. This consistent performance has helped the series build unstoppable momentum since its debut, where it immediately launched straight into the No. 1 position.

Now, just weeks into its run, the drama has accumulated more than 46.6 million total views worldwide. That figure places it firmly in fifth place among all Korean Netflix originals in the platform’s history, a staggering achievement for such a recent release. In doing so, it has officially overtaken The Glory, which previously stood at 39.7 million views. The gap between the two now sits at nearly 7 million views, a significant margin that highlights how quickly viewing habits are shifting in favour of the new hit.

The rapid rise of Teach You a Lesson has not been limited to a single region. The series has demonstrated broad international appeal, breaking into the Top 10 across 75 countries and regions. Even more impressively, it has reached the No. 1 position in six different markets, including major entertainment hubs such as Hong Kong, Japan, and Indonesia. This level of cross-regional success is rarely achieved so quickly, especially for a newly released Korean drama competing against established global franchises.

The show itself is based on a popular webtoon of the same name and revolves around a fictional government agency created to defend teachers’ rights. The storyline follows members of the organisation as they intervene in cases of abuse, systemic neglect, and institutional failure within the education system. The mix of social commentary, emotional storytelling, and high-stakes drama has clearly resonated with audiences worldwide, helping the series build a loyal and rapidly growing fanbase.

Industry analysts suggest that part of the show’s appeal lies in its timely subject matter, as education-related issues continue to spark debate in multiple countries. Combined with fast-paced storytelling and a strong ensemble cast, the series has managed to connect with viewers far beyond its domestic audience, contributing to its explosive global performance.

While Teach You a Lesson has been stealing the spotlight, other Korean titles have also maintained a strong presence on Netflix’s global charts. Agent Kim Reactivated secured the No. 3 spot on the Global Top 10 Non-English TV Shows list with 6.6 million views, continuing its own steady performance. Meanwhile, Brave New World landed at No. 7, and Notes from the Last Row followed closely at No. 8, reinforcing the continued strength of Korean content on the platform.

Despite this broader success, it is the rise of Teach You a Lesson that has dominated conversation. Its ability to outpace long-established hits, maintain global No. 1 status for multiple weeks, and rapidly climb into Netflix’s all-time top five Korean series has positioned it as one of the most significant breakout hits of the year.

For The Glory, once considered untouchable in its cultural impact and streaming numbers, the shift marks a rare dethroning in a space where top rankings often remain stable for extended periods. Its fall to sixth place in the all-time ranking underscores just how aggressively new content is reshaping viewer preferences on a global scale.

As Teach You a Lesson continues its run, attention is now turning to whether it can sustain its momentum long enough to challenge even higher positions in the all-time rankings. With weeks of strong global performance already behind it and no clear slowdown in viewership, the drama’s trajectory suggests this may be more than just a passing viral hit—it could be a defining global success in Netflix’s Korean content history.
